How big can a redback spider grow?
A brown recluse is not a large spider. It is about the size of a lead weight that you would put onto a fishing line. The brown recluse and the black widow are two poisonous spiders found in the US. Neither one has enough poison to kill a person. The danger is that their bites cause infection, which can damage large areas of tissue. The bite of a brown recluse usually turns black within a few days, and swells up around the bite.
The Black Widow venom is approximately 15 times more powerful than a Rattlesnake's venom. The venom is a powerful nuerotoxin. The obvious insight is that a Black Widow is not injecting as much venom as a Rattlesnake could. At 15x the potency though you have a concern on your hands.
A Black Widow bite can potentially cause death in a human being. As noted in other texts, the most common deaths are the very young and the very old. However, each bite is case specific. One individual may not react like another. There may be a strong reaction to the venom in one individual and less severe response in another.
Why take a chance? If you are bitten by a Black Widow go the ER and state up front that you have been bitten by a Black Widow. Antivenin is available should it be warranted.
Yes, their egg sacs contain hundreds of eggs. Before they lay their eggs they will eat the male (go figure). Then, after they lay their eggs they will die.
Are Brown recluse spider found in Canada?
The range of Brown Recluse spiders is at least heading up in that direction. Whether there are such spiders in Kelowna or not is probably something that only city or provincial officials keep statistics on. The biology department of the nearest university might be another good place to ask.

Give 2 reasons for why spiders are not insects.?
The main reason is that spiders and several other little animals such as scorpions split of from the main evolutionary branch going one way, and insects split off from the main branch going another way, and that happened a very long time ago.
The related reason is that the physical structures of spiders and insects are the same in that they do not have bones inside their legs and other body parts (so they have exoskeletons and are arthopods), but other than that almost everything about them is different.
Will wolf spiders eat brown recluse spiders?
Wolf spiders and praying mantises eat each other. If one is bigger than the other, and is hungry, the larger of the two will likely eat the smaller. If they are both about the same size, it depends who sees who first, and who is hungrier. In the northeast U.S., large wolf spiders and large Chinese mantises compete for food all the time, and only the adult female Chinese mantises can overpower and eat adult wolf spiders. Usually the mantis can avoid being bitten by using the dexterity of it's forelegs to re-position it in such a way that the spider's fangs cannot reach any part of the mantis. The mantis then slowly will eat the spider alive. But if the spider is on the hunt, and sneaks up behind a mantis that is not paying attention, one quick bite would probably be enough to subdue the mantis. This has been studied extensively in northeast U.S. meadows, where both large wolf spiders and large praying mantises live. Look at the book "The Praying Mantids" by Dr. Frederick Prete. It's very technical, but the info is there. It's a bug-eat-bug world out there.
Why is thick steel wire stronger than thin steel wire?
The material will yield when stress reaches a critical value.
Stress = Load / Area
Thick steel wire is stronger than thin steel wire because there is more cross sectional area in the thick wire. Although the material's strength in load per unit area would be the same, the ultimate load that the wire can sustain would be more in the thick wire. A simple way of looking at it is to imagine a thick wire as a number of thin wires stuck together. If a thin wire can support a mass of 1kg then 2 thin wires can support 2kg. A wire which is twice as thick (twice the cross sectional area) can also support 2kg.
